Fast-charge stations can provide an electric vehicle with a full charge in less that 30 minutes, according to Carol Noble, the port’s director of environmental plans and programs.

Separately, the port plans to install slow-charging stations for electric vehicles in the Disney Cruise Line long-term parking garage, which port Chief Executive Officer John Walsh said was a suggestion of Disney officials, stemming from requests of Disney customers.

That project will cost less than $10,000 for engineering, design and equipment, Noble said.

About 1,000 new plug-in vehicles (which include all-electric vehicles, such as the Nissan LEAF) are registered in Georgia every month, according to Don Francis, executive director of Clean Cities-Georgia. Eighty percent of those cars are registered in metro Atlanta.

Atlanta is the No. 2 market nationwide for electric and plug-in hybrids and the No. 1 market for the Nissan LEAF, Georgia Power spokeswoman Amy Fink said.

The research firm studied the total cost of owning a hybrid, and found that 10 of the 31 hybrids included in the research were more cost-effective to own that their gasoline counterpart. The percentage of cost-effective hybrids has fallen to 32 percent from 39 percent in the 2013 study and 44 percent in the 2012 study.

The Lexus CT200h and the Toyota Avalon Hybrid returned impressive lower ownership costs with savings of over $7,600 and $3,200 respectively. Additional hybrids from Acura, Audi, Honda, Hyundai, Lexus, Lincoln, and Toyota also showed cost advantages, according to Vincentric.

However, when the costs to own and operate all 31 hybrid vehicles were taken into account, the average five-year cost-of-ownership for hybrids was $1,339 more than their gasoline-powered counterparts.

This strong result is also on the heels of August, when Nissan set a new all-time record for fully electric sales in the US (and the world) by selling 3,186 copies, while bringing its share of the plug-in space in America up to almost 25%.

Overall for the year to date, Nissan has sold 21,822 LEAFs, an improvement of 36% over 2013 when 15,896 were moved.
